PROBLEM TO BE SOLVED: To provide an information processing system allowing the use of electronically acquired information in the use of a coupon, the payment of a price, the receipt of a commodity or the like without converting it to a hardware-like medium. SOLUTION: This system comprises a management server connected to a user's portable terminal and a store terminal set in each store through a communication network and equipped with an information database with prescribed electronic information stored therein. When required electronic information is requested from the portable terminal through the communication network, the management server extracts the corresponding electronic information from the information database, converts it into a bar-code image data, and transmits the bar-code image data to the portable terminal together with an applet for adjusting the display screen of the portable terminal so as to clearly display a bar-code on the display screen of the portable terminal through the communication network to display it on the display screen. The store terminal reads the bar-code information displayed on the display screen of the portable terminal through a bar-code reader and performs a service processing corresponding to the bar-code information. |
